It lifted the dirt and grease right off of my ride which surprisingly isn't brown. I needed something to really get off all of that caked on grease, and this was it and it worked like a charm. The [$] bottle lasts many washes. One bad thing is the smell. It's nice at first, but it gets old when it follows you on your hands wherever you go.

I use this on my carbon road, steel tandem, Ti road (old bike now a commuter). It just works! Leaves a little bit of a coating behind that seems to make the next cleaning easier. I have never used a 'bike cleaner' assuming it is just another gimmic. I was pleasantly surprised.
